Before you begin
•
Reassign all the VMs to a port group on a different distributed switch or standard switch.
Otherwise, an error occurs when you attempt to delete the VMware vSphere ESXi host from the
VMware VDS.
•
Migrate all VMKernel ports to a different distributed switch or standard switch.
•
Distributed port groups and uplink adapters do not need to be removed.
VMs network adapters assigned to a distributed port group will force an error when attempted to delete
the ESXi host from the VMware VDS. All the VMs are assigned to the distributed port group need to be
reassigned to a port group on a different distributed or standard switch. The VMware VDS that is being
removed must have all the VMKernel ports either migrated to a different standard Switch or VMware VDS
or be removed.
After reviewing the prerequisites, perform the following procedures:
1 vMotion/evacuate all powered on VMs from the VMware vSphere ESXi host
2 Migrate VM distributed port group assignments
3 Migrate the VMkernel ports to a different switch
vMotion/evacuating all powered-on VMs from the VMware vSphere ESXi host
Evacuate/vMotion all powered-on VMs to a different VMware vSphere ESXi host to free up the ports on
the VMware VDS. VMs can still point to the same distributed port groups from a different VMware
vSphere ESXi host, because there are no assigned VMs on the host.
About this task
This procedure requires using the migration VM network wizard that migrates all the VMs port
assignments to a different switch with no downtime. If this option is not possible due to the number of
VMs or a shortage of system resource capacity, refer to Migrating powered-on VMs distributed port group
assignments to a different switch.
Before you begin
Ensure sufficient system capacity exists on other VMware vSphere ESXi hosts to migrate all the powered-
on VMs.
Procedure
1 Open a browser and type the following URL: https://<vCenterIP>:9443/vsphere-
client You can also launch the VMware vSphere Web Client by selecting Start Menu > All
Programs > VMware > VMware vSphere Web Client. The alternative launch method above
does not apply to vSphere 6.5.
2 Log on to the VMware vSphere Web Client with the administrator@vsphere.local user account
(VMware vSphere SSO account) or other administrative account with appropriate permissions.
